Re: [AMaViS-user] virus scan size limit?

> There are two kinds of size limits:

I should add: there is also a set of (generous) size limits
designed to stop runaway decoding on mail bombs:

$MAXLEVELS = 14;                # (default is undef, no limit)
$MAXFILES = 1500;               # (default is undef, no limit)
$MIN_EXPANSION_QUOTA =      100*1024;  # bytes  (default undef, not enforced)
$MAX_EXPANSION_QUOTA = 300*1024*1024;  # bytes  (default undef, not enforced)
$MIN_EXPANSION_FACTOR =   5;  # times original mail size  (default is 5)
$MAX_EXPANSION_FACTOR = 500;  # times original mail size  (default is 500)

Mail bomb is not checked for viruses to protect virus scanners
from falling into a trap. The message is wrapped into another MIME
layer, prepended with a warning text, tagged with warnings in the
header, and passed. MTA can be configured (through header checks)
to block such mail or put it on hold or (usually) just pass it.
